Alan;
Many thanks for your further clarification. It is interesting to note that you said 'warangan' has been a part of malay language usage. I as a Malay from Kelantan myself has never encounter this word until fairly recently when I got involved in keris collecting. Of course me not knowing this word does not mean that it was not a part of an original malay word and I am no linguist so I can not say you are wrong in this respect.
I have to defer this point to other more learned people in the forum. (they must be lurking somewhere as "CCTV" ...)
